Application filed September 13, 1910. Serial 110,581,789;

To all whom t mayo con'cgrn: p

Be itknown that I, ALEXANDER H. EVANS, a lcitizen of the United lStates,residing at Freeporain the county of Stephenson and State of Illinois,have 'invented a new and useful Device for'Utilizing Solar Heat, ofwhich the following is a specification.

This invention relates to a new and useful device for utilizing solarheat, whereby a quant-ity of water may be easily and readily heated, andthen stored for the purpose of.

being conveyed to various localities for use. The invention aims as itsessential object to provide a' device of this design, in iwhich anincasement is mployedto contain the.

water to be heated. For'examplethe incasement is made air tight, and isprovided upon its interior with an apparatus having transverse passageways, intov which the' m-water is advanced. These transverse passagewaysare 'formed by the provision ofa pair of 'corrugated sheet metalplates.

A further. feature of this invention is the production of longitudinalslotted pipes,

into the slots of which the corrugatedV plates are brazed, for allowingthe water to enter the passage ways. a

.-A further object of the invention, resides in means for storinglthelheated water.` 3@ This means comprises a-sto'ragej tank, in` closedby a casing having a felt lining, in

order to confine the heat., This casing is provided with a hingedclosure and'a catch therefor, whereby access may be had to the interiorofthe casing. The water is conveyed from any suitable source of supply(not shown) through one pipe to the 'incasement (which is with aglasstop) it isthen carried from 3W the incasement to the storage tank, fromwhich it may lbe utilized as desired. These pipes are provided withsuitable valves whereby the inflow and the outflow of the i d Water maybe easily controlled The drawing onlydiscloses one` form of the presentinvention, but however in puracfV tical fields this form may necessltatesllght alterations, to which the applicant -is entitled, provided the'alterations are compre- In the drawings-Figure'l is a view in provided'allowingthewater to advance to the vheater @naar oir@- ratenteaoot.29,191.2..

section of the apparatus, showing the various and from the same, andfurther showing the device composed of the corrugated plates'V arrangedwithin the incase-ment. Fig. .3 is

a perspective view of the devicewhich is located within theincasement... Fig. 4 is a'de-v tail view in section of a portion of thedevice shown in Fig. 3, showing the manner in 'which the corrugatedplates are secured by brazing in the slots of the pipes.-

' s tothe. drawings, 1 designates an ineasement having a glass cover ortop 2. This glass cover or top is secured to the incasement by thestrips 3, which form, a

.groove 4 to receive the' glass. This glassv cover or top is for t-heVpurpose of allowing the suns rays to act direct upon the watercontaining;l receptacle 5. rIfhis receptacle- 5 is composed of a pair ofsheet metal corrugated plates 6 and 7, the edges of which are providedwith strips or pieces 8, which are' arrangedbetween the corrugationsupon the upper and Alower surfaces of said plates, as shown clearly inFig. 3. These strips or' pieces 8 are brazed in the slot's- 9 of thepipes 10 and 11, as shown clearly in Fig. 4. 12 and V13 denote plateswhich are brazed or otherwise connected to the extremities of the pipes10 and 11, in order to close the ends of f said pipes.

To convey the water to 4the receptacle,

and especially to the interior ofthe pipe 10 a pipe 14 is providedhaving a valve 16, in order to control. the How of water. The .pipe 14connects with any suitable supply (notshown). After the water has b eenthoroughly heated, the same is carried from` the receptacle by 'means ofthe pipe 15 (which is provided with a valve 17 Vcontrollingthe water).The pipe '15 enters the casing 18 andextends upwardly and over thestoi'agev tank 19. The top of the storage tank is provided with a valve20, with which the pipe 18 connects; 'By this valve th/e water maybecontrolledfupon the interior of the casing 18, as well as by the valve17. This 'casing 18 is lined upon its innercircumference by! a layer` offelt, or

is provided with a closure 22, hinged at 23 and provided with a springclasp 24:, to engage a hook or projection 26, to permit the closure tobe held securely inl place. 'Leading from the storage tank is a pipe 2g,whereby the -water after being heated and stored maybe conveyed tovarious localif ties. For example, the stora e tank and its Vcasing maybe arranged in a dwelling or l l'tion thereof, while the heatermay' bearranged upon the roof, in order to-permit other structure, preferablyintheupper porthe sunsrays to squarely shinethereupon. rlhe pipe 27 isprimarily used for.connect.

" ing with .a plurality of pipes 28, which are designed to communicatevand terminate with faucets or spigots at various points throughout the:dwelling: By this arrangement water may be conveyed to toilets, the

kitchen and other points in the dwelling.

lThe pipe27 has a valve 29 whereby the water may be controlled tothesevarious sure, a receptacle including opposed spaced apartcorrugated metal members, whose l'edges are provided with stripsarrangeduponthe'upper and lower. surfaces of said plat-es, lateral. tubular.members having longitudinal slots, within c7which slots are brazed said.

` strips, plates secured to, and forming clo- 4sures. for the ends ofsaid tubular members,

supply and'delivery pipes. connected to said tubular members, and atank, said delivery pipe also' connecting with said tank, at its upperend. y

2. A solar heater, including an air-tight incasement,l a heat-conductingclosure for said incasement, said^incasement comprising opposedcorrugated metal-members, having alternate contacting and spaced apartsur faces, adapted to form numerous tubes, said contacting surfacesbeing in the median line ofthe incasement, lateral tubular membershaving longitudinal slots, said corrugated tubeforming members havingcommunication with said lateralA tubular members through the slots ofthe latter, filling-in members between said corrugated members and theopposed edges or walls. of said slots, and end-plate closures for saidlateral tubu lar members, an incased storage tank, pipe connectionlbetween one of said .slotted lateral tubular members and said storagetank, and-circulation pipes for said storage tank nd the other slottedlateraltubular mem- .In testimdony that I claim the foregoing as my own,I have hereto affixed my signa-` ture in the presence of twowitnesses.
